Hi Bob M.,
I have been lurking here and paid a visit to the MU Flat Panel WEB site which I got from Barb or Joan, sorry lousy memory.
I was hopeful of finding something about a diamond based thin film technology you mentioned over in the ISSM thread. I didn't find that at MU but I did find a link to some groups reports on the status, prospects and problems of the various Japanese solutions to the holy grail of Flat Panels.
It was very interesting and very technical, which I am not; but it did seem to be clear from the authors' comments that (a) the Japanese are ahead as you have indicated, and (b) none of the current solutions are final, set or right for all uses.
The performance spec.s given for various types of systems of a given size were telling. From the standpoint of performance (eliminating cost and ease of manufacturing) the best system design, from the standpoint of being able to handle most of the uses you and Barb have mentioned, was a ferroelectric effort.
Its main drawbacks seemed to be in the area of manufacturing difficulty and cost and the absense of grayscale capability, if I recall the info correctly. Generally, I look at materials based design problems as being the most important, i.e., copper wire is copper wire and will not give you the impedence of wood no matter you do to it. (This is a very untutored analysis :- ) Manufacturing problems on the other hand I consider to be more a problem of throwing time, money and EE talent into the mixer.
Thus if the performance sought has the potential to justify the resources needed to correct the mfg. problems, I would put my money on the design with the best performance. So at long last my questions:
1) How important is the absence of "grayscale" in a Flat Panel? and
2) Is this ferroelectric effort in Japan based upon a diamond thin film or something else?

P.S. If I am so far off base with these questions that you are forced to consider closing down this thread, please feel free to ignore them. :- )
